Scott, who has dated Jenner since April, began informing people close to him that he's going to be a father almost two months ago, according to TMZ.

Meanwhile, a surrogate is reportedly currently carrying a child for Jenner's half-sister, Kim Kardashian and her husband, Kanye West, with a due date expected in mid-January, according to the gossip site.

This timeline would mean the two babies would arrive around the same time.

It's also worth noting that Jenner's ex, the rapper Tyga, has sparked speculation that he's really the father of Kylie's future child. After news broke of Jenner's pregnancy last Friday, Tyga posted a photo to Snapchat reading "hell nah that's my kid" before quickly taking it down, as seen in screen grabs captured by fans.
